Which term describes a positive reproduction of dental arches used to study occlusion or articulation?

Understanding how upper and lower teeth meet relies on a physical model of the arches. This model is a positive reproduction created by pouring stone into an impression, giving a tangible copy you can examine outside the mouth. This is called a study model or cast and it’s used to study occlusion and articulation, check how teeth contact each other, and plan restorations or adjustments, often mounted on an articulator to simulate jaw movements. An impression, by contrast, is the negative mold taken of the teeth, not the final model. A die represents a single tooth portion for precise fabrication like crowns, not the full arch. A wax pattern is used during the restoration fabrication process, not as a full-arch reproduction for occlusion study. So the term for the positive reproduction of dental arches used to study occlusion or articulation is the study model or cast.
